C.1 Zones with Blocks

When zooming into the Blocks in a Zone, we look at deviation from the mean score in the Zone, so 0 is equivalent the Zone average. If the score values were normally distributed (like a bell curve) around the average, then one standard deviation (SD) above/below is about 34.1% higher/lower than the average (so 68.2% of all values), two SDs is 47.7% higher/lower than the average (so 95.4% of all values) and three SDs are the most extreme at 49.9% higher/lower (so 99.9% of all values).
